Rainstorms from Nigeria, Benin expected to trigger thunderstorms across Ghana — GMet warns
The Ghana Meteorological Agency (GMet) has warned of widespread thunderstorms and rain across parts of the country as rain-bearing systems currently affecting Nigeria and Benin move westwards into Ghana.
According to GMet's latest 24-hour weather forecast, valid from 6:00 p.m. on June 10, 2026, mostly cloudy conditions are expected nationwide this evening, but weather conditions are likely to deteriorate as the advancing rainstorms enter the country.
The agency said the weather system is expected to generate thunderstorms and rainfall of varying intensities from the evening through to the night, raising concerns about possible flooding in vulnerable communities.
GMet cautioned that strong winds are likely to precede the rainstorms, increasing the risk of damage to property and disruption of outdoor activities. It further warned that flash floods could occur in low-lying areas, especially locations with poor drainage systems, saturated grounds and choked waterways.
The forecast indicates a high probability of thunderstorms with rain across several major towns and cities, including Accra, Kasoa, Ho, Koforidua, Kumasi, Obuasi, Sunyani, Techiman and Aflao during the evening hours. Some localities in the middle and northern sectors are also expected to experience thunderstorms and rain before conditions gradually improve overnight.
By early Thursday morning, mist or fog patches are expected to form along the coast, forest zones and mountainous areas, potentially affecting visibility for motorists and commuters.
In the Greater Accra Region, Accra and Kasoa are both expected to experience thunderstorms with rain this evening, while coastal cities such as Cape Coast, Takoradi and Axim could also record rainfall activity.
The agency advised the public to take precautionary measures, particularly residents in flood-prone communities, as the unstable weather conditions move across the country.
Meanwhile, GMet reported that sea conditions remain rough, urging fishermen, canoe operators and other marine users to exercise caution.
The latest advisory comes as parts of Ghana continue to experience seasonal rainfall associated with the peak of the major rainy season, with meteorologists closely monitoring weather systems developing across West Africa.
